Be it known thut ll, JOWEPI-I lln'unurj, a citizen oi? the United States, end u of Glilfton. coimty o-E Psssuic, and State oi. New Jersey, have him l certain iew and useful improvements in lohscro :hredding .JllJPdl'BtllE-, oit which the hvllowinpr is u spot i iicstion.

My improvements relate especially to the shredding and reducing opt remnents of tobecco lest for use as filling materiel or snulopgous purposes in the art of preparing tobacco for connnerciul purposes, and the main object of my invention is to afford simple, inexpensive, but elllective eppurutus adapted for the purp se in which the u e of knives is dispensed with, and provi on is mode for ell'ectuelly regulating); and grading the product.

To this end the invention consists in the specific rombinution and urrungement of ports and so 'ences described end claimed; -dis'inctive esturesconsi mgin the use of a series of rotatable discs or -g; peripheral dish sting pins and luterul disintegrating pins protuberunt from either side there of, in conjunction with Sli'lillOlWl discs on which are positioned rcsrdsnt studs which intervene between the said later .1 disintegrating pins on the rotatable discs, by which means the tobacco ripped and. torn apart ml reduced to fragments; in the provision for screening and grading the product, end in this cornice" in the use of s screen "for this purpose in which prori is made for ediustiiug' the ores of the outlets while mum ing the gn'escribed square shape tl'iereol'; and in the use of air exhaust means for Witl'ulruwingz' the product, when suitably reduced, tlu'ough seid screen, and discharging it from the uppurutus; the invention also including certain minor details 1.? construction, oil as hereinafter lolly forth.

ltigidly mounted upon and between parallel horizontal members F, F, of a suitable "Er-rune Work is 2. basic skeleton shell consisting of end discs 5, Z), connected by a. bottom member I), on which letter are intermediate discs or partitions b 5 In the construction shoym in the drawings two of these intermediate partitions b ,'b (Fig. 3) are provided, although one or any plural number thereof may be incorporated in the upgqrstus, according to the requisite size and cupucity thereof. The end discs l), b, are formed with external bearing extensions 6', 7), in which is journzrlled s rotatable shuft 9, upon one extremity of which is rigidly rnted s driving pulley S, as shown more pa ticulorly in Figs. 1, and 5, of the drawings.

Mounted upon and between the end discs (5, Z) is rectsngulsr frume C, 2, l and 5) having; end members (2, 0, concentric with. and fitting; upon the upper edges of said end discs 7), Z), and also formed with longitudinal side members 0, c. On this rectangular frame C, is mounted the hopper ll, arranged to deliver tobacco through the opening; C. (Fig. 4-.) in said irume C, to the disintegrsting;- cylindrical chamber D. The letter is formed between the end discs or members 5, Z), of the skeleton shell, referred to, and contains the stationery partitions 5 l), which subdivide said disintegrating churnher into compartments.

Rigidly mounted on the shaft El, within the disintegrating; chamber 1), and between the intermediate discs or partitions F2 32 are spider hubs s, 3, formed with equidistant redial. arms 5, s, as shown more psrtioulurly in Fig. 3. Rigidly protuberant from the ends of: the spider arms 3, e, are disintegrating pins s s and also rigidly protuberunt from the sides of said spider shifted on the side wall screen arms 3, s, are lateral disintegrating pins s 8 so positioned as to intervene hot-ween concentric rows of retardant studs Z) Z), rigidly protuherant from the fixed partitions 6 b and the end discs 6, b, as will be seen by reference more particularly to Figs. 2, 3 and l, of the drawings.

The cylindrical side walls of the disintegrating chamber D are formed of approximately semi-cylindrical plates (5. (Z, secured as shown in Fig. 3, to the end discs 6 and t0 the intermediate discs 6 These wall plates cl, (Z, extend from the bottom nieniher Z), of the skeleton frame to the longitudinal members a, c, of the rectangular top frame C, as shown more particularly in Each wall plate 0 (Z, is ,"orniel i 1: ries of outlet apertures riZ, cl, of square shape and uniform area. as s :own pa .1- larly in Figs .5 and 6, constituting a screen through which the tobacco passes when Sulliciently reduced for the purpose.

Fitting upon the peripheral surfaces of these wall side plates (Z. (Z, are supplementary screen plates A, A. mounted adjusv ably with relation thereto and also formed ar a.

F1 discs 7), b, as shown more particularly in F 3 and 8. The flanges a, a, are "formed with diagonal slots 01 (F. s... f tioned at an angle 0:? as related to the longitudinal axis of the shaft S) for the ac comniodation of the studs (5?. d"; prci'izu ant from the. said extensions (5?, (Z of the side wall plates (5.15, the studs he screw threaded for the reception or hinding: nuts (Z (5 as sl'iown Figs. 1.

Furthermore l dispense entirely with the use of rollers and reduction knives, which cut the tobacco up unevenly and create Waste, besides Wl'iich the knives soon get out oi. order and have to be replaced, Whereas my retardent and disintegrating pins are not injured by nails and any other foreign matter frequently encoui'itered in the ordinary tobacco leai supply. The absence of gearing in my apparatici is also to be noted,-only a single rotatable shaiit boin g1; employed in connection with the disintegrating}; chamber, in which latter the leat tobacco is ripped and torn apart, in contradistinction to the old method oi. reduction by cutting.
